Lightning Data Upgrade - NEW

Lightning Events

In December 2014 we upgraded our lightning network to the latest in sensor technology as used by the world's leading meteorological agencies. This has resulted in changes and improvements to the lightning data you will now see. The main changes are:

Distance and latitude/longitude coordinates are displayed when you mouse over the map. The
origin for distance measuring is indicated by a red dot and defaults to either your location, if specified and in range, or the location
of the radar/the centre of the map. The origin may be changed by clicking elsewhere on the map.

The colours and symbols used on the radar and satellite maps are described on

Radar Details

Dampier Radar has an unrestricted 360 degree view from its site 50 metres above sea level, and though no major permanent echoes appear, a small amount of low intensity clutter may be visible around parts of the coast and the islands surrounding Dampier and offshore to the west. Dampier Radar is susceptible to a small amount of false echoes on land during the dry months. These echoes are characterised by erratic movement and very low intensities. During the wet season between December and March anomalous propagation may cause significant false echoes to appear for distances up to 60 kilometres along the coastline and seaward of it. During the wet season (primarily January to March), thunderstorm clouds and cyclonic formations are generally well defined for distances up to approx 250 kilometres. Beyond hat distance signal attenuation gives the appearance of less intensity than possibly exists. These formations are easily identified from false echoes by their regular rates in movement and direction. Thunderstorm activity can be viewed generally on a daily basis during the wet season, general preferred locations are in a trough line from the southwest to the southeast of Dampier/Karratha in and about the ranges. Heavy rain directly over the radar site can cause attenuation of all signals. Path attenuation can also occur when the radar beam passes through intense rainfall, with the returned signals from cells further along that path reduced.
